Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural products and Chinese herbal medicine drying industry, and relates to a multi-material inlet feeding retrogression stacking direct-inward cross-air duct air inlet box-type dryer. Background Technique

[0002] At present, the drying of agricultural products and Chinese herbal medicines in the industry uses multi-layer mesh belt reciprocating circulation dryers and single-layer mesh belt direct-inward dryers. When the multi-layer mesh belt reciprocating circulation dryer works, hot air enters from the bottom of the bottom mesh belt, penetrates the materials on multiple mesh belts to reach the upper feeding layer, and directly discharges the mixed air. When the single-layer mesh belt direct-inward dryer works, hot air enters from above and below the indirectly longitudinally segmented mesh belt respectively, and the hot air penetrates the materials. When the single-layer mesh belt dryer works, hot air is dried by setting the upper and lower air inlet convection circulation air duct method. Although it is improved compared with the previous technology, the drying quality and throughput still cannot meet the development status far.

[0003] In summary, the existing mesh belt dryers have the following disadvantages:

[0004] 1. The existing mesh belt dryers all enter air from the bottom of the mesh belt and feed materials on a single-layer mesh belt. They need to dry in multiple round trips to reach the discharge port, with low working efficiency.

[0005] 2. When the existing multi-layer mesh belt dryer works, the upper part feeds at a low temperature and the lower part discharges at a high temperature. The overall drying process temperature cannot be adjusted, and it cannot adapt to the appropriate temperature required for drying different materials at each drying stage. Moreover, the high-temperature dry materials at the discharge port are prone to fire.

[0006] 3. Each dryer requires a worker to operate at the feeding port and the discharge port respectively. Since it is a single-layer mesh belt running in a reciprocating cycle, the feeding amount and the discharging amount cannot meet the workload of the workers, restricting the working efficiency of the workers.

[0007] 4. The single-layer mesh belt material is dried in a reciprocating cycle to the discharge port. After the drying operation starts, before the drying operation ends, when the material quantity is too small for long-term drying operation, and when the material quantity is too small to fill the multi-layer reciprocating mesh belt, inevitable ineffective work of empty drying operation will occur, greatly increasing the production cost and the working cost.

[0008] 5. Whenever moisture is discharged from the bottom layer, it will affect the drying and moisture discharge of the upper layers of materials, greatly affecting the drying efficiency and the color and quality of the items.

[0009] 6. After the hot air penetrates the upper layers of materials from the bottom, it is impossible to separate the moisture and the dry hot air, so that the remaining hot air cannot be recycled. Summary of the Invention

[0025] The beneficial effects of the utility model are:

[0026] 1. The existing technology is that the air is taken in from the bottom of the bottom mesh belt, and the single-layer mesh belt is used for feeding. It needs to go through multiple round-trip cycles to dry before reaching the discharge port, which has low work efficiency.

[0027] The technical advantages of the utility model are: independent mesh belt conveyor modules are stacked and straight-forward, each layer of single-machine mesh belt cross-air duct simultaneously intakes air for drying, the feeding flap conveyor can realize multi-layer mesh belt conveying and simultaneous feeding, and one-way straight-forward driving. Compared with the existing technology, multiple dryers work at the same time, and the drying efficiency is significantly improved.

[0028] 2. In the existing technology, the material is fed at low temperature at the top and discharged at high temperature at the bottom. The material is dried at the same temperature from the feed to the discharge. The appropriate temperature required for each drying stage of the material cannot be adjusted, and fires often occur when the dried material is discharged at high temperature.

[0029] The technical advantage of the utility model is that the material is transported by a multi-layer mesh belt that moves horizontally and straight through units that are longitudinally divided into multiple horizontal air inlet units. Each air inlet unit can independently and arbitrarily adjust the appropriate temperature required by the material in each drying stage, completely eliminating fire and greatly improving product quality and color quality.

[0030] 3. With the existing technology, each dryer's feeding port and discharging port require a worker to operate. Since the feeding port is fed by a single-layer mesh belt and it runs reciprocatingly to the discharging port, the feeding amount and discharging amount are far from meeting the normal workload of the workers, which objectively limits the workers' work efficiency.

[0031] The technical advantages of the utility model are: the multi-layer mesh belt conveyor feeds materials at the feeding port at the same time, and runs in parallel to dry to the discharging port, and the multi-layer mesh belt conveyor discharges materials at the same time. The input and output throughputs meet the workload of the workers, and the work efficiency and production efficiency are doubled.

[0032] 4. Although the existing technology is a multi-layer mesh belt circulation drying, it is actually a single-layer mesh belt reciprocating circulation drying to the discharge port. Therefore, when the drying operation starts to feed, the entire interior of the dryer is in an empty operation; before the material discharge of the dryer is completed, the entire interior of the dryer is also in an empty operation; when the amount of material is too small to feed the entire mesh belt, the dryer will more or less produce the empty operation that exists when the dryer is operating. The empty operation of the dryer is an invalid operation, which greatly increases the production cost.

[0033] The technical advantage of the utility model is that no matter after the feeding of the drying operation starts, or before the discharge of the materials in the drying operation ends, or when the amount of material is too small to feed the entire machine mesh belt, an independent drying cycle operation can be selected as appropriate, or multiple drying cycles with suitable temperatures can be connected in series, which completely solves the ineffective work of the empty-belt drying operation and significantly reduces the production cost.

[0034] 5. With the existing technology, hot air enters the drying process from the bottom, and the hot and humid air discharged from the materials dried by the bottom mesh belt penetrates the materials on the upper layers of the mesh belt along with the hot air flow, affecting the drying and dehumidification of the materials on the upper layers, thus affecting the drying efficiency and the color quality of the dried items.

[0035] The technical advantages of the utility model are: the horizontal air duct intakes air for drying layer by layer, each layer dehumidifies independently and performs secondary dehumidification, which prevents the dehumidification from affecting each other, makes the drying hot air purer and drier, and improves the quality, color quality and drying efficiency of the dried materials exponentially.

[0036] 6. With the existing technology, after the hot air penetrates the upper layers of materials from the bottom, it is impossible to separate the hot and humid air from the dry hot air, so that the remaining hot air cannot be recycled.

[0037] The technical advantage of the utility model is that the remaining dry hot air after the secondary dehumidification can be directly recovered and reused, and can also be recovered and sent to the heat source for repeated heating and utilization as appropriate, thereby greatly reducing the production cost.

[0038] 7. In the existing technology, the multi-layer mesh belt conveyor reciprocating cycle setting is a conjoined structure setting, which cannot be divided into independent and fixed monomers, and cannot be factory-produced and modularly maintained.

[0039] The technical advantages of the utility model are: an independent mesh belt conveyor module machine is set, and then a plurality of independent mesh belt conveyor modules are constructed into a main box by a step-back stacking method, which reduces useless height, increases drying layers, and reduces energy consumption. The various box-type components of the hot air unit are fixed independent stereotyped modules, and the parts of the multi-feeding flap conveyor structure are also independently set stereotyped products. The utility model can be modularized for factory production, modular movement, replacement, maintenance and other fast operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0098] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0099] Embodiment 1: Feeding by mechanically powered flap (18). ⑴. Refer to Figure 3 、 Figure 4 、Figure A、 Figure 22 、 Figure 23 、 Figure 24 、 Figure 46 、 Figure 47, when the opened flap (18) moves forward along with the chain (49) to the U-shaped pallet (20), the flap (18) will move along the short plane at the upper opening of the U-shaped pallet (20) and be lifted one by one by the plane. The flap (18) flips to form a flap belt for conveying materials. At this time, the first flap lifted by the U-shaped pallet (20) is called the set flap. The shaft column (52) connected to the set flap in a shaft manner is the shaft column (52) provided in the pawl chain assembly (113) set to be installed here. The pawl chain assembly (113) here is called the first pawl chain assembly (113). At the other two places at a distance of one-third of the total length of the front and rear full chains from here, two more, namely the second and third pawl chain assemblies (113), are also set to be installed. For the flaps (18) at the set positions of the pawl chain assemblies (113), there are flap notches (24) corresponding to the pawl heads (54). The purpose is to enable the pawl heads (54) to pass through the flap notches (24) smoothly when the set flap rotates without hindering the free rotation of the flap. When the above-mentioned first pawl chain assembly (113) moves forward beyond the U-shaped pallet (20) and touches the return wheel (31) of the first group of rotating pallets (21), all the previous rotating pallets (21) are in the opened state. This place is called the lower feeding opening. When the pawl head (54) in the first pawl chain assembly (113) pulls the return wheel (31) of the first group of rotating pallets (21), it will drive the rotating pallet (21) to rotate around its fixed shaft (33). When the rotating pallet (21) rotates to a certain position, the pawl head (54) will disengage from the return wheel (31) and continue to move forward. The rotated pallet (21) that has completed the reset replaces the U-shaped pallet (20) to hold the flap (18) to form a flap belt for conveying materials. The pawl head (54) that continues to move forward will pull the second, third,... until it pulls the last group of rotating pallets (21) to complete the reset and hold the flap (18). The pawl head (54) disengages from the return wheel (31) and continues to move forward with the first pawl chain assembly (113). At this time, the material is also conveyed to the upper feeding opening. ⑵. Refer to Figure 3 , Figure 4 , Figure A, Figure 18 , Figure 19 , Figure 21, when the following pawl chain assembly (112) moves forward to a set position from the upper feeding opening, the pawl wheel (34) will press against the boosting plate (42), pushing the pushing pawl (45) to drive the opening wheel (30) to move forward together. The rotating support plate (21) will rotate around its fixed shaft (33). When the rotating support plate (21) rotates to a certain position, it will disengage from the turning plate (18). Multiple turning plates (18) that lose the supporting force will simultaneously rotate around the shaft columns (52) on the left and right sides. The conveyed material will fall into the corresponding multiple hopper boxes (73) along with the multiple rotating turning plates (18) for feeding. When the pawl chain assembly (112) moves forward to the set position of the upper feeding opening, the top plate (37) on the pawl shaft (38) will touch the screw head (50). Under the resistance of the screw head (50), the top plate (37) rotates with the pawl shaft (38) to drive the pawl wheel (34) to rotate with the pawl arm (41). When the pawl wheel (34) rotates to a certain position, it will disengage from the boosting plate (42) and continue to move forward with the pawl chain assembly (112). The pawl wheel (34) returns to its initial position and stops statically under the combined action of the return spring (39) and the positioning pin (40). The slide plate pushing pawl (43) that loses the forward driving force returns to the initial positions on both sides along the chute (46) under the pulling force of the tension spring (114). All the rotating support plates (21) opened on both sides stop in the open state and move with the chain (49). ⑶. Refer to Figure 3 , Figure 4 , Figure 38 , when all the rotating support plates (21) in the feeding port are simultaneously opened for feeding, the second pawl chain assembly (113) reaches the lower feeding opening, and the following pawl chain assembly (112) also approaches the lower feeding opening. When they respectively operate in combination with their corresponding pulling, rotating, and resetting combination operation (23), pushing, rotating, and opening combination operation (22), the above combination operation actions will be repeated. One rotating support plate (21) is reset to support the turning plate (18) to continue conveying the material, and the second rotating support plate (21) opens the turning plate (18) to realize multi-port feeding again. Similarly, when the third pawl chain assembly (113) and the following pawl chain assembly (112) reach the set positions respectively, they will also operate in combination and repeat the above actions, achieving the purpose of multi-port turning plate feeding. The material falling into the multiple hopper boxes (73) will be spread evenly on the multiple belt conveyors (2) where they are located by multiple material leveling devices (67) and conveyed to the main engine box (7)

[0100] In this embodiment: The power-driven flap (18) is used for feeding. Components such as the magnet holder (116), touch sensor head (117), iron frame chain reset combination (118), iron frame chain opening combination (119), double-sided armature (120), iron rod head (121), reset coil (122), opening coil (123), double-sided DC electromagnet (124), normally open proximity switch (127), first reset coil terminal (X), second reset coil terminal (X1), first opening coil terminal (Y), second opening coil terminal (Y1), etc. are used to replace components such as the rotating support plate (21), sliding claw combination (48), rotating pawl (B), (B1), pulling claw (D), (D1), etc. Refer to Fig. (50), Fig. (51), Fig. (52), Fig. (53) ( Figure 54 ), Fig. (55), Fig. (56). When the flap (18) lifted by the U-shaped support plate (20) moves to the lower feeding opening and approaches the first group of double-sided DC electromagnets (124), the touch sensor head (117) in the iron frame chain reset combination (118) in front of the flap (18) approaches the normally open proximity switch (127), which starts the normally open proximity switch (127) to close. The output current starts the control relay at this position to close, conducting the reset coil (122) in the electromagnet (124) at this position to be energized. The coil generates a magnetic field to attract the double-sided armature (120) to drive the iron rod head (121) to extend towards the bottom of the flap (18) for resetting. The reset iron rod head (121) supports the moving flap (18) and acts as the U-shaped support plate. When the flap (18) supported by the iron rod head (121) moves forward to the next group of double-sided DC electromagnets (124), the touch sensor head (117) in the iron frame chain reset combination (118) will similarly approach and start the normally open proximity switch (127) at this position to close. The reset coil (122) in the second group of double-sided DC electromagnets (124) will be energized, generating a magnetic field to attract the double-sided armature (120) to extend and insert for resetting. The iron rod head (121) extends to support the flap (18) to transport materials. By analogy, the iron rod heads (121) in each group of double-sided DC electromagnets (124) arranged in sequence on the left and right sides will also be inserted for resetting in sequence. When the last iron rod head (121) is inserted for resetting to support the flap (18) and moves forward to the upper feeding opening, the touch sensor head (117) in the lagging iron frame chain opening combination (119) approaches the normally open proximity switch (127) at the set position, triggering the normally open proximity switch (127) to close. The output current starts the control relay in this circuit to close, conducting the opening coils (123) in all the double-sided DC electromagnets (124) on the left and right sides to be energized. The coil generates a magnetic field to attract the double-sided armature (120) to retract in the opposite direction of the flap (18) and withdraw the iron rod head (121) to open the flap (18). The materials transported on the flap (18) all fall into the funnel box (73) as the flap (18) rotates. Repeating the above actions can achieve multi-feed opening feeding.

[0101] In this embodiment: drying operation. ⑴. When the material coming from the feeding port is conveyed to the main chassis (7), refer to Figure 1 , Figure 2 , Figure 36 , Figure 37 , Figure 38 , Figure 48 , Figure 49, in the future, the high-temperature hot air coming from the heat source is sent into the first high-temperature box (4), the third high-temperature box (4-1), the second high-temperature box (4-0), and the fourth high-temperature box (4-2) through the high-temperature hot air inlet air door (3) provided on the first high-temperature box (4). Open the high-temperature hot air outlet push-pull movable door (57) provided on the first high-temperature box (4) to allow the high-temperature hot air to enter the first air duct box (5). Turn on the cold air induced draft fan (63) provided on the first air duct box (5), adjust the regulating valve (16) provided at the cold air outlet at the top of the first air duct box (5), and control the magnitude of the cold air intake volume of the cold air outlet holes (107) on the cold air duct (61) to achieve the adjustment of the mixed temperature of the high-temperature hot air and the cold air, so that the appropriate drying temperature required by the material enters the first induced draft fan box (6). The cold air induced draft fan (63) in the first air duct box (5) can be turned on or off according to the temperature required for material drying. The hot air induced draft fan (65) in the first induced draft fan box (6) blows the hot air at the appropriate drying temperature into the main machine box (7) provided with a plurality of air inlet mesh plates (81) and a plurality of drying chamber air inlets (84) provided in the cross-air exhaust unit (7-1). Turn on the cold air induced draft fan (63) provided on the first induced draft fan box (6). The cold air blows towards the hot air induced draft fan (65) through the cooling duct (68) to cool the body, and then is discharged out of the box through the cooling duct air outlet (15). The hot air entering the plurality of cross-air exhaust drying chambers (71) in the cross-air exhaust unit (7-1) penetrates the material on the conveying mesh belt (80) upwards in the set direction, and then mixes with the hot air entering from the air inlet mesh plate (81), and together flows towards the mixed air outlet (82) provided on their respective layers, and then enters the moisture exhaust box (8) through a plurality of mixed air inlets (89). The multi-layer moisture separation plates (91) provided in the moisture exhaust box (8) separate the mixed air into hot and humid air (108) and dry hot air (85). The hot and humid air (108) is discharged towards the moisture exhaust outlet (88) provided on its respective layer. Through the first integrated box (9) provided with a plurality of moisture exhaust fans (95), the hot and humid air (108) discharged from the moisture exhaust outlet (88) is diverted to the moisture exhaust duct (94) provided in the first integrated box (9), and then is discharged out of the box through the moisture exhaust duct air outlet (12).The dry hot air (85) enters the first integrated box (9) through a plurality of dry hot air outlets provided in the dehumidification box (8), and then passes through a dehumidification fan (99) for secondary dehumidification, so that the dry hot air is drier and free of moisture. The remaining hot air in the first integrated box (9) is recovered to the waste heat recovery channel (77) through the waste heat recovery outlet (78), the regulating valve (16), and the waste heat recovery induced draft fan (102). The regulating valve (16) and the waste heat recovery induced draft fan (102) provided therein can be opened or closed as appropriate. The top of the first integrated box (9) is provided with a regulating valve. The high-temperature hot air in the high-temperature hot air compensation duct (11) is guided to the high-temperature hot air compensation duct (11) provided in the first integrated box (9), and then enters the first integrated box (9) through the high-temperature hot air compensation air outlet (104). The high-temperature compensation hot air entering the first integrated box (9) is mixed with the dry hot air in the box to form warming hot air, and then flows to the warming hot air outlet door (93) provided in the first integrated box (9). At this point, the high-temperature hot air completes the drying operation of the cross-air removal unit (7-1) on the materials in the main box (7). (2) Refer to. Figure 49The heated hot air from the first integrated box (9) passes through the heated hot air outlet door (93) provided in the first integrated box (9), passes through the heated hot air inlet door (106) provided in the second air duct box (5-1), flows to the heated hot air outlet door (93) provided in the second air duct box (5-1), and then enters the first induced draft box (6). The first induced draft box (6) is provided with a hot air induced draft fan (65), which blows the heated hot air into the main box (7). The cross-flow air unit (7-2) is provided with a plurality of drying chamber air inlets (84) and a plurality of air inlet mesh plates (81). The hot air entering each cross-flow air drying chamber (72) penetrates upward in a set direction through the material on the conveying mesh belt (80), and then combines with the hot air entering from the air inlet mesh plate (81). The mixed air flows together to the mixed air outlet (82) of each layer and enters the dehumidification box (8). The dehumidification box (8) is provided with multiple layers of dehumidification plates (91) to separate the humidity and separate the mixed air into hot and humid air (108) and dry hot air (85). The hot and humid air (108) is discharged to the dehumidification outlet (88) provided on the layer, and is passed through the second integrated box (9-1) provided with multiple dehumidification fans (95). The hot and humid air (108) discharged from the dehumidification outlet (88) is guided to the dehumidification duct (94) provided in the second integrated box (9-1), and then discharged out of the box through the dehumidification duct outlet (12). The dry hot air (85) passes through the dehumidification box (8) provided with multiple dry hot air outlets (86) and enters the second integrated box (9-1). The dehumidification is then performed for a second time through the dehumidification fan (99), and the dry low-temperature hot air is also called residual hot air. There are two options for the operation of the residual hot air: one is to choose recovery. In the case that the next unit needs to suspend the drying operation, or the next unit needs a higher temperature drying operation, then the hot air aisle air inlet opening and closing movable door (55) provided in the first air duct box (5) of the next unit, i.e., the horizontal air removal unit (7-1), is closed, and the waste heat recovery induced draft fan (102) and the regulating valve (16) are opened to recover the residual hot air to the waste heat recovery channel (77) through the waste heat recovery air outlet (78) provided in the second integrated box (9-1), the waste heat recovery induced draft fan outlet (101), and the waste heat recovery connecting pipe (13); the other is to choose to continue In the case of the next unit requiring a low-temperature drying operation, the waste heat recovery induced draft fan (102) is turned off, and the hot air passage inlet opening and closing movable door (55) provided in the first air duct box (5) of the next unit, the horizontal air removal unit (7-1), is opened to allow the remaining hot air to continue to run into the first air duct box (5) in the next drying cycle. The high-temperature hot air outlet push-pull movable door (57) provided in the second high-temperature box (4-0) is opened as appropriate to adjust the size of the high-temperature hot air inlet volume, and then mixed with the remaining hot air to achieve the appropriate temperature hot air required for drying, and enter the first induced draft box (6) for drying operation. At this point, the high-temperature compensation hot air completes the horizontal air unit (7-2) drying operation of the main box (7). The horizontal hot air completes a one-way drying operation, which is a drying cycle. Repeat the above multiple drying cycle operations to dry the material and transport it to the discharge section.⑶, Refer to. Figure 2 , Figure 38 , the high-temperature hot air flows out from the hot air outlet damper (56) provided in the third high-temperature box (4-1) of the last cross-air supply unit (7-2), enters the fourth high-temperature box (4-2) through the high-temperature hot air inlet damper (3) provided in the fourth high-temperature box (4-2), and then enters the third air duct box (5-2) through the push-pull movable door (57) provided in the fourth high-temperature box (4-2). The remaining hot air in the second integrated box (9-1) of the upper unit also enters the third air duct box (5-2) through the hot air duct inlet air opening and closing movable door (55) provided in the third air duct box (5-2). The high-temperature hot air and the remaining hot air are mixed to form the hot air at the appropriate temperature required for the material discharging stage and then enter the second induced draft fan box (6-1). The second induced draft fan box (6-1) is provided with a hot air induced draft fan (65) to blow the hot air at the appropriate temperature out of the bottom hot air inlet (75) into the discharging section.
